Abstract (en)

[origin: WO2022234222A1] The present invention relates to a molding composition that comprises by weight: (a) 20 to 60 wt.% of at least one long-chain aliphatic polyamide having a number of carbon atoms per nitrogen atom greater than or equal to 9, said at least one polyamide having an inherent viscosity in solution less than or equal to 1.3, as determined according to the standard ISO 307: 2007, at a temperature of 20°C; (b) 40 to 75 wt.% of glass fibers; and (c) 0 to 5 wt.% of at least one additive, the sum of the proportions of each constituent of said composition being equal to 100%, excluding an amorphous polyamide and a microcrystalline polyamide.
